If you are looking for information ---- You came to the right place!!
Others will chime in but for starters, the map of the trails (snowmobile trails) you have is not legal for ORV use. If you have a secretary of State liscence plate and insurance any route legal for a car (seasonal road/snowmobile trail) would be legal. Be aware that sections of snowmobile trails many times are routed through private property and thus are off limits to any wheeled vehicle. It is only legal to operate an orv on designated trails and use areas, if it is not marked open for orv use it is off limits (state land). It is legal to operate an orv on any private land with the land owners permission. If your bike(s) are not plated and insured you have to stick to designated trails and areas marked for orv use or you run the risk of harrasement, tickets, bad plublicity for the rest of your dirt bikeing brothern and ultimately the closure of the legal areas we do have.
